Help!

I have an old boiler and it keeps tripping the electric once I turn the heating on. Every time I turn it on my TV it goes off.

The lights are ok but when I go to the consumer unit and turn the switch back it comes back on.

I havent much oil so have ordered a good lot now just in case this was causing the problem and too much power was being used to run it. Any ideas or will I have to get an engineer out?

Btw my box inside is an old looking Horstmann Coronet H425 and my boiler outside is a WILO GOLD 50.
Sorry Im not technically minded so please keep it simple!Thanks a lot

Sorry forgot to say when I turn that switch on its supposed to show an orange light and you can then hear the boiler going outside.Now the light comes on for a millisecond then off and the TV trips.My boiler is not working
